Часто осыпаются завязи огурца в теплице


Часто осыпаются завязи огурца в теплице
Скорее всего, это связано с нарушением питания растения. У огурца очень крупные листья, они испаряют много воды, и культуру приходится часто поливать. При этом из почвы в нижние слои вымываются быстрорастворимые элементы азота и калия.

Калийное голодание растений — одна из причин опадения завязей. Они также опадают при низкой температуре воздуха и почвы, в первую очередь у партенокарпических гибридов, у которых при температуре ниже +14-15° С усвоение питательных веществ снижается.

Особенно опасна низкая температура ночью. Если она ниже +15 ° С, рост завязей резко сдерживается. Опадание их может происходить и при недостатке света, если посадка загущена. При этом пчелам трудно добраться до цветков. Обрежьте лишние побеги или прищипите их. Регулярно, через каждые 10-12 дней, подкармливайте растения.

В холодные ночи раньше их укрывайте. Некоторые огородники наливают в пластиковые емкости воду и расставляют их по краям гряд. Днем они нагреваются от солнца, а ночью отдают тепло.
